Wettability surface control on stainless steel by LIPSS formation

Abstract

In this paper, laser-induced periodic structures are obtained on the surface of SS304 stainless steel when treated with femtosecond laser radiation. The dependence of the period of surface structures on the speed and power of laser radiation treatment is revealed. The wetting angle and the dependence of this angle on the processing speed are determined. It is shown that after femtosecond laser treatment, the surface became more hydrophilic.
